A Process For Removing Halide Compounds Adhering To Finely Divided Metal Oxide Particles By Means Of Steam
Process for removing halide compounds adhering to finely divided metal oxide particlesby means of steam, whereto the metal oxide particles are applied to the upper part ofan upright column and migrate downwards by means of gravity, the steam is applied atthe bottom end of the column, the metal oxide particles and the steam are fed counter-currently, the metal oxide particles freed of halide residues are removed at the base ofthe base of the column, steam and halide residues are removed at the head of thecolumn, wherein the column is heated in such a manner that the temperaturedifference Tbottom Ttop between the lower part and the upper part of the column is atleast 20°C and a maximum temperature of 5000C prevails in the column, and the metaloxide particles have a residence time in the column of from 1 to 30 minutes.
